本文研究了一类长度大于0的常循环BCH码,其中q为素数幂,为偶数。确定了长度大于1000的狭义厄米特对偶含常循环BCH码的最大设计码距。此外,还得到了这些常循环BCH码在给定设计距离下的精确维数。因此,我们能够推导出量子码的参数,作为相关常循环BCH码的设计参数的函数。这改进了Yuan等人最近的结果。(Des Codes Cryptogr 85(1):179-190,2017)对于具有相同长度的代码,除了三个平凡的情况()。而且,我们新构造的量子码中的一些量子码与最近构造的量子码相比具有更好的参数(Song等人,Quantum Inf Process 17(10):1-24,2018,Aly等人,IEEE Trans Inf Theory 53(3):1183-1188,2007,Li等人,Quantum Inf Process 18(5):127,2019,Wang等人,Quantum Inf Process 18(10):1-40,2019)。
In this paper, we study a family of constacyclic BCH codes overof length, whereqis a prime power, andan even integer. The maximum designed distance of narrow-sense Hermitian dual-containing constacyclic BCH codes overof lengthnis determined. Furthermore, the exact dimensions of these constacyclic BCH codes with given designed distance are obtained. As a consequence, we are able to derive the parameters of quantum codes as a function of their designed parameters of the associated constacyclic BCH codes. This improves a recent result by Yuan et al. (Des Codes Cryptogr 85(1): 179–190, 2017) for codes with the same lengths except three trivial cases (). Moreover, some of our newly constructed quantum codes have better parameters compared with those constructed recently (Song et al. Quantum Inf Process 17(10): 1–24, 2018, Aly et al. IEEE Trans Inf Theory 53(3): 1183–1188, 2007, Li et al. Quantum Inf Process 18(5): 127, 2019, Wang et al. Quantum Inf Process 18(10): 1–40, 2019).
